Be it known that I, UGUSTUS SCHMIDT,

a c tizen of the United States, residing at Indianapolis, in the oountyof Marion and State of Indiana, haveinvented certain new and useful Iin rovements in Rotatable Dis tributing-Npzz es, of which the following is a s eolfication.

his invention relates to a rotatable nozzle f or water distributing purposes, and is. particularly applicable in equipping build ings to protect them against fire; and the for spraying lawns, trees, etc.

The object of the invention is a rotating nozzle for distributing water which is arranged so that the nozzle will be positively rotated by the action ofthe water.

The object consists, lurther, in a-nozzle of the above described character havin a fusible release device so that" a-fireconuguous thereto will automatically set the nozzle into operation. r

I accomplish the objects of invention" by the nozzle illustrated in the accompanying drawings',-which forms a partthereof, .in

which Figure l is an underside plan view of my nozzle. Fig. 2 is a side elevation of'the nozzle. .Fig. 3,. is a central vvertical sectional view of the nozzle. 'Fig. '4 is a cross section of the fusible locking device, on the dotted line 44 i-nFig, 2. ,1 I

In the draw' s, 1 constitutes a spher-' ical hollow shell h iijch forms thedistributing part of the nozzle proper. 'Theshell 1 provided with a vplurality"of long narrow vertically extending slots 2 cut on a line so that narrow vertically extending sheetsof water will be discharged backward .cnfa tangent with the line of rotation. "The shelll is also provided with. an inlet apr-y ture at its top, said-aperture being rovided with threads to receive the threade endo'fa" portion of said race is formed byian'aimular ring 6. Thering'fi is provided on itsinner peripheral flange 7 with-threads which. en-

gage threads on the exterior surface of the expanded. portion of the sleeve 10. Snugly fitting the interior-diameter oflthe collarB is i a secondary collar 12, having its lower and under edge out flaringly to form a valve-seat,

to I provide and the collar is provided at'its'up per end with a spider 15 which permits the water-to pass uninterru'ptingly. The upper and outer edge ofthe secondarycollar 12 is beveled which edge engages a corresponding surface formed on the interior 10. The secondary col ar-12 has slight ver- 2 tical movement within the collar 3, permitted by the sldt 13, but it is held independently'against rotation ofthe collar 3 by.

ineansjo a' screw 14-, which passestransversely throu h the wall of the collar?) and ortion of the sleeve engages the s 0t: 13 in the secondary collar 12. The object of errnittinga slight vertical movement of tl ie secondary collar 12 is to permit it to be seated against the beveled surface on theflinterior of the sleeve 10, and thus prevent-water from escaping through the ball-race whemthe nozzle is not in opera- 'tion. It willbe readily understood that the ball-race'co'uld not be acked. to prevent the discharge of water and still reduce the friction to permit the nozzle to rotate freely, when in operatio1i.- The secondary collar 12 is moved into its uppermost osition when the valve is seated so as to c ose the inlet to the nozzle.

As before'stated, the secondary collar is provided with a spider15 having a centrally threaded aperture to which the screw propeller 20 isseo'u'red. The upper end of the screw propeller is provided with a spindle 21 which engages an aperti'ire in the spider 22 formed in'the mouth of the sleeve 10. v The "upper and exterior surface of the sleeve 10 is provided with threads so that proper con- -'nectio1i can bemade with the nozzle. Thus, it will be seen that as the'water enters the *sleeve 10it will cause the'propeller 20 and the shell l to rotate. .The nozzle is, provided with a valve 30 which normally closes the inlet to the hollow shell 1, and is provided with a stem 31 which extends downward and passes through an aperture in the yoke 34. The yoke 34 is provided with an integrally formed boss 35, the latter having exterior threads to engage the threaded aperture in the lower end of the shell 1.. Theyoke 34 is, also, provided at each end with the extension 36, and said extensions are provided with the slots 3' which These plates are pivotally connected to the extensions. by means of the trai-sver'se I pins 39. IWhen the plates 38 are secured together bymea'ns of fusible metal they supreceive the overlapping fusible plates 38.

. port the lower end of the valve-stem 31 and old the valve 30 in its uppermost position.

When the plates 38 are separated by the heat melting the fusible metal, the valve is permitted to drop and the nozzle is thus automatically set into operation. The overlapping plates 38 are provided with a plurality of apertures into which I insert the blocks 46, which extend across the combined thickness of the two plates and thus helps to sustain the weight, thereby reducing the stress on the fusible metal.

The relative width of the blocks 46 and the thickness of the plates 38 is best shown in terfering with the action of the valve-stem 3 1; when the lates 38 separate, I form theslots '37 somew at wider than the thickness of the plates, and the opposite sides and ends of Fig.4. I

11 order to prevent the plates 38 from insaid slots are beveled to permit the plates to spread, thereby leaving an unobstructed passageway for the downward movement of said valve-stem 31'. The position occupied by said plates 38 when separated is clearly shown by the dotted lines in Fig. 1. 5 Having thus fully described my said invention, what I desire tosecure by Letters Patent, is

' '1. A revoluble water distributing nozzle comprising a hollow globular shell provided with a' plurality of water discharging slots, a hollow sleeve forming the inlet to said shell,

, a primary collar rigldly engaging the shell the internal wall-of, the inlet sleeve, .means permitting longitudinal movement between the collars, the sleeve and the shell,

and a valve normally to close the inlet to said nozzle,

comprising a hollow width-Ta plurality and abutting means to prevent separation of.

esasa 3. A revoluble water distributing nozzle comprising a hollow globular shell provided with" a plurality of water discharging slots, a hollow sleeve forming the inlet to said shell, a primary collar rigidly engaging the shell and projecting into said inlet sleeve, a secondary collar extending lon itudinally through the primary collar and abutting the internal wall of theinlet sleeve, means permitting longitudinal movement between the collars, a valve normally to close the in] ct to said shell, means for moving said valve to close the inlet to the nozzle, and means for securing said valve in a determined po sition.

4. A revoluble water distributing nozzle globular shell provided of water discharging slots, a hollow sleeve forming the inlet to said shell,

"a primary collar rigidly engaging the" shell and projecting into said inlet sleeve, a sec ondary collar extending longitudinally through the primary collar and abutting the internal wall of the inlet sleeve, means permitting longitudinal movement but preventing circumferential movement between the collars, means to prevent separation of the sleeve and shell, and a valve normally to close the inlet to said shell.

5. A revoluble water distributing nozzle comprising a hollow globular shell provided with a plurality of water discharging slots,

. a hollow sleeve forming the inlet to said shell.

a primary collar rigidly engaging the shell and projecting into said inlet sleeve, a secondary collar extending longitudinally through the primary collar and abutting the internal wall of the inlet sleeve, means permitting longitudinal movement between the collars, means to prevent separation of the sleeve. and shell, a propeller arranged within the inlet sleeve and rigidly engaging and moving both longitudinally and circumferentially with the secondary collar, and a valve normally to close the inlet to said shell. In witness whereof, I, have hereunto set my hand and seal at Indianapolis, Indiana, this 15th day of July, A. D. one thousand nine hundred and seven.
